No they don't If they did, surely you'd be riding a Da Bomb or Base TA26? Like Ad said, watches all tell the same time, but some are worth more than your cars and some are less than a fiver. Like anything, there are items with special touches, better materials, better design, more exclusivity etc etc. Tak cufflinks as a very basic example. ALL they do is stop your cuffs coming apart. You could use a split pin. But there are ones that cost £15 grand.
